As it happens, JREF has almost 2000 followers, so the synchronicity is too much to resist. So, when my BadAstronomer account reaches 20,000 tweeps, I will donate $200 to the JREF. It just seems like the right thing to do, since the JREF gets most of its operating costs through donations. When I donate the money I'll do it through
the JREF donation page. I also set up
Twitpay for the JREF, so anyone on Twitter can follow suit quickly and easily if you're signed up for it.
